Abstract

The zone adjacent to the bottom of a groove 4 which accommodates a compression ring 6 is placed in direct communication with the high-pressure surroundings via passages 9 produced in the body of the piston 1 or in the compression ring. Such passages allow the pressurised gases coming from the combustion chamber to quickly reach the zone of the groove 4 behind the compression ring 6, thereby pressing said ring against the surface 2 of the cylinder barrel and thus obtaining an optimal seal, even with a minimum axial play between the upper and lower walls of the groove and the compression ring. <IMAGE>
